AMERICAN NATIONAL STANDARDS ON ACOUSTICS The Acoustical Society of America (ASA) provides the Secretariat for Accredited Standards Committees S1 on Acoustics, S2 on Mechanical Vibration and Shock, S3 on Bioacoustics, S3/SC 1 on Animal Bioacoustics, and S12 on Noise. These committees have
7、wide representation from the technical community (manufacturers, consumers, trade associations, organizations with a general interest, and government representatives). The standards are published by the Acoustical Society of America as American National Standards after approval by their respective S
8、tandards Committees and the American National Standards Institute (ANSI). These standards are developed and published as a public service to provide standards useful to the public, industry, and consumers, and to Federal, State, and local governments. Each of the Accredited Standards Committees (ope
9、rating in accordance with procedures approved by ANSI) is responsible for developing, voting upon, and maintaining or revising its own standards. The ASA Standards Secretariat administers Committee organization and activity and provides liaison between the Accredited Standards Committees and ANSI. A
10、fter the standards have been produced and adopted by the Accredited Standards Committees, and approved as American National Standards by ANSI, the ASA Standards Secretariat arranges for their publication and distribution. An American National Standard implies a consensus of those substantially conce
11、rned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity.
12、 Consensus requires that all views and objections be considered and that a concerted effort be made towards their resolution. The use of an American National Standard is completely voluntary. Their existence does not in any respect preclude anyone, whether he or she has approved the standards or not
13、, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the Standards. NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodic
14、ally to reaffirm, revise, or withdraw this Standard.

As such, this Foreword may contain material that has not been subjected to public review or a c
23、onsensus process. In addition, it does not contain requirements necessary for conformance to the standard. This standard comprises a part of a group of definitions, standards, and specifications for use in acoustics. It was developed and approved by Accredited Standards Committee S1 Acoustics, under
24、 its approved operating procedures. Those procedures have been accredited by the American National Standards Institute (ANSI). The Scope of Accredited Standards Committee S1 is as follows: Standards, specifications, methods of measurement and test, and terminology in the field of physical acoustics,
25、 including architectural acoustics, electroacoustics, sonics and ultrasonics, and underwater sound, but excluding those aspects which pertain to biological safety, tolerances, and comfort. This standard supplements ANSI/ASA S1.11-2014/Part 1/IEC 61260-1:2014 American National Standard Electroacousti
26、cs Octave-band and Fractional-octave-band Filters Part 1: Specifications. This standard is an identical national adoption of IEC 61260-2:2016 Electroacoustics Octave-band and fractional-octave-band filters Part 2: Pattern-evaluation tests, which was prepared by IEC/TC 29. However, in conformance wit
27、h ANSI and IEC rules, the words “this part of ANSI/ASA S1.11/IEC 61260” replace the words “this part of IEC 61260” where they appear in the IEC document, decimal points were substituted in place of the decimal commas used in IEC documents, and American English spelling is used in place of British En

33、or assessments of conformance to performance specifications, ANSI/ASA S1.11/Part 1/IEC 61260-1 uses different criteria than were used for the IEC 61260:1995 edition. IEC 61260:1995 did not provide any requirements or recommendations to account for the uncertainty of measurement in assessments of con
34、formance to specifications. This absence of requirements or recommendations to account for uncertainty of measurement created ambiguity in determinations of conformance to specifications for situations where a measured deviation from a design goal was close to the limit of the allowed deviation. If
35、conformance was determined based on whether a measured deviation did or did not exceed the limits, the end-user of the octave-band and fractional-octave-band filters incurred the risk that the true deviation from a design goal exceeded the limits. To remove this ambiguity, IEC Technical Committee 29
36、, at its meeting in 1996, adopted a policy to account for measurement uncertainty in assessments of conformance in International Standards that it prepares. This edition of ANSI/ASA S1.11/Part 2/IEC 61260-2 uses an amended criterion for assessing conformance to a specification. Conformance is demons
37、trated when (a) measured deviations from design goals do not exceed the applicable acceptance limits and (b) the uncertainty of measurement does not exceed the corresponding maximum-permitted uncertainty. Acceptance limits are analogous to the tolerance limits allowances for design and manufacturing
38、 implied in the IEC 61260:1995. Actual and maximum-permitted uncertainties of measurement are determined for a coverage probability of 95 %. Unless more specific information is available, the evaluation of the contribution of a specific filter or filter set to a total measurement uncertainty can be
39、based on the acceptance limits and maximum-permitted uncertainties specified in this standard.
